African migrants try to reach Europe in the hope of finding a better life
The United Nations' human rights commissioner has condemned as "inhuman" the European Union's policy of intercepting migrants in the Mediterranean and returning them to Libya.
In a statement issued from Geneva, Zeid Raad Al Hussein said African migrants were enduring horrific conditions in Libyan detention facilities. He called it an outrage to the conscience of humanity.
According to figures from the government in Tripoli, almost 20,000 migrants are being held in Libya. Last month detainees told UN investigators they were subjected to beatings and sexual violence.
They described being packed into warehouses without functioning toilets.
